Changing the extension on "The Little Shop of Horrors" files worked(!), but "The Phantom Empire" now has a 2.6GB Ogg derivative.

later...

I deleted the OGV file, and changed the extension for "The Phantom Empire" to MPEG4.

ok, i *think* your items and derivs look good now?

the one i was most curious now about was
http://www.archive.org/details/The_Phantom_Empire_1935

looks like you maybe removed the derivs and renamed your orig file from .mp4 to .mpeg4 and then a normal derive just kind of "worked" -- does that sound about right?


btw, i'm not sure this will work per se (depends a bit on the mpeg4 source) -- but do you know about "qt-faststart" (most easily found and buildable in source of "ffmpeg" as a subdirectory util). but in the future, you can often use it to move the "mov" atoms related to video information from the end to the start of the file. that will often make a video "play more instantly" when dropped into a mp4 playable browser like safari or versions of firefox-- and when dropped into a flash plugin (thought i saw some feedback in forums or on one of the items could be related?) (if, say, all that info is at the end of the mpeg4 -- the flash plugin or [video] tag in a /details/ video playback page will tend to require the client browser to *first* download the *entire* file before it will start -- eek! 8-)

just in case that helps at all!

cheers,

Yes, I did those things.

Thanks for the info on qt-faststart. I found a pre-built Mac app that I hope will fix the demuxed edited MPEG4 files I make as you describe. Very glad the .mp4 to .mpeg4 trick worked.
